Blancpain caliber 6054F
Self-winding movement with annual calendar and second time zone. This self-winding movement requires just one date adjustment per year, at the transition from February to March. For all other months, the watch itself moves on from the 30th or the 31st to the first day of the following month. It also has a small 24-hour hand in a subdial at 8 o’clock, which serves as a reference time. The GMT function is provided by the central hour hand of the watch, which is linked to the date. The generously sized date apertures are arranged in such a way as to ensure optimal readability.
